“…Once the blackouts have occurred, the appropriate system restoration should be performed. Most blackouts are partial and can be restored with the support of neighboring regions [3,4]. On the other hand, if total blackouts occur, neighboring regions may be not able to assist the system, especially for isolated power systems such as Korean power systems.…”

When a blackout occurs, it is important to reduce the time for power system restoration to minimize damage. For fast restoration, it is important to reduce taking time for the selection of generators, transmission lines and transformers. In addition, it is essential that a determination of a generator start-up sequence (GSS) be made to restore the power system. In this paper, we propose the optimal selection of black start units through the generator start-up sequence (GSS) to minimize the restoration time using generator characteristic data and the enhanced Dijkstra algorithm. For each restoration step, the sequence selected for the next start unit is recalculated to reflect the system conditions. The proposed method is verified by the empirical Korean power systems.

“…Although the standards and some general guidelines [4] are provided, the restoration operations are still highly stressful for system operators. After a major outage or blackout event, the system operators in the control center will conduct series of restorative control actions to restart generations, to re-establish transmission networks, and to pick up the interrupted loads, until the power gird recovers to a normal operation condition.…”

This paper proposes an optimization model to compute optimal load restoration plan for the transmission network. The objective of this model is to maximize the load pickup subject to power flow constraints and discrete load increment constraints. This mix-integer optimal power flow model (MIOPF) is solved via a branch-and-cut (B&C) framework. The nodes in the B&C tree are solved by the interior point method. In particular, three cutting planes, namely, the Gomory rounding cut, the knapsack cover cut, and the fixing variable cut, are incorporated into each node of the B&C tree to reduce the scale of the sub-tree. This model can be used to aid the system operators to conduct load restoration actions or draw up a restoration plan. The load restoration plan is obtained by solving a number of co-related MIOPF models till all load increments are restored. The RTS 24-bus test case with 170 load increments (i.e., with 170 binary variables) is used to illustrate complexity of the proposed model and the computational efficiency improvement stemming from the cutting planes.

This paper is concerned about islanding of network and observability of these islands in power system restoration. It is assumed that a black out happened on a system which have minimum PMUs (phasor measurement units) for measuring network's parameters. To restore this system an algorithm of islanding that keeps all islands observable to make the restoration process shorter is introduced and developed step by step on the IEEE 14 bus system and it is applied to the New England 39 bus system to show the result for a bigger system.
